Due to their material base of intrinsically active materials (phase-changeable polymers), the ICs are suitable for large-scale integration and offer the possibility of active decision-making capabilities regarding chemical information.
The microchip presented in this paper shows an example of such a µCHMS IC based on intrinsically active materials.
Additionally, the research will discuss the suitability of an alternative material base to fabricate channel structures and especially the separating membranes Acknowledgements We would like to thank the German Research Foundation (A.R., M.A.), the Saxon State Ministry for Science and the Arts and the European Science Foundation (R.G.) for funding.
